9.3.5 Plasma Circuit
Plasma/buffer pump (PBP)
(marked yellow)
Peristaltic roller pump with motor switch-off when the pump
cover is open
Delivery rate:
2 ÷ 50
ml/min
Delivery rate variation:
< 10
%
Working pressure range:
-100 ÷ +450
mmHg
Protection system:
Pump status and rate is monitored via a rotation detector.
Alarm override:
Not possible during the therapy
Acoustic alarm interval:
120
s
Plasma pressure (PPL)
Electronically measured by a pressure sensor and digitally
displayed
Measurement range:
- 500 ÷ +500
mmHg
Allowed tolerance
± 10
mmHg
Working range:
+20 ÷ +50
mmHg
During Therapy:
Default alarm limits:
-10 ÷ +200
mmHg
Lower limit adjustable in parameter setting
Protection system:
Sensor test during preparation phase.
Alarm override:
Not possible during the therapy
Acoustic alarm interval:
120
s
Blood leak detector (BLD)
Photometrical red detector on disposable tubing close to plasma
filter outlet
Sensitivity:
0.25
%
(For detecting 0.5 ml of blood in 200 ml of fluid)
Avoid direct light exposure!
Reaction time:
approx. 20
s
Protection system:
Automatic calibration and self-test during preparation
phase and cyclic self-test during therapy.
Possibility of repeating the calibration/self-test at alarm
during therapy.
Alarm override:
Possibility for alarm overriding during therapy when the
self-test/calibration failed three times. The therapy can be
continued with monitoring by the user.
A periodically occurring warning is maintained.
Acoustic alarm interval:
120
s
